PACKING DEVICE FOR FILLED-CAN-CLOSING MACHINES.

Application filed November 5, 1928. Serial No. 146,444. I

The invention relates to new and useful improvements in packin devicesforfilled can closing machines, and more particularly to a packingdevice which operates to depress the floating content of the can. I

An object of the-invention is to provide device of the, above'charactcrwith means whereby any floating content which overlies the flanged edgeof the can body may be 3Q cut off, so as-to permit the floating contentbe forced downinto the can body without leaving any content inengagement with the flange.

I A further object of the invention is to provide a device of the abovecharacter, wherein the pad or head which moves down into "the can bodyfor depressing the floating content thereof, is provided with a recessand perforations or openings leading 2Q therefrom to the face of the pador head, whereby the liquid content of the can body may pass up into therecess and subsequentiy drain back into the can when the pad or head isremoved therefrom.

3 These and other objects will in part be obvious and will in part behereinafter more fully described.

in the drawings which show b i lustration one embodiment of t e 30tion-- Figure 1 is a view part1 in front elevation and partly in sections owing a portion of a closin machine having theimprovements appliedthereto; Fig. 2 is an enlarged sectional view through the packing head,also showing the body which is being entered by the packing head, andFig. 3 is a lower front view of a portion of the packing head.

The invention is directed to a acking device for a filled can closingmac ine, which is so constructed as to depress the floating content ofthe can rior to the passing of the can body into the closing machine. Ithas been found in practice, that often some of 'the floating content,particularly in connection with string beans, is likel to overlie theflange on the can body, an when the packing head comes down to depressthe floating content, this overlying portion is clamped againstthe-flange and is not depressed. The overlying portion of the contentwiii then go into the closing machine 51% overlying the flange, and whenthe cover is way of lnvenwhich surrounds t placed, this content worksinto the double seam and causes a leak. The present invention isdirected particularly to the construction of the packing head, wherebmeans is provided for severing the over tion of the content, sothatremaining in the can into the can body. This is accomplished .byplacing on the packing head, a cutter,

e packing head, and so as to move down ying porthe content is. spacedtherefrom over the flange of the can body and thus sever any contentlying on the flange and extending beyond the same. This packing head isalso provided with a recess or chamber and with perforations leadin fromthe lower face of the pad or head on t e packing device into said recessor chamber. mits the liquid content of the can to pass up into saidrecess or chamber without overflowing the can, which is quite anadvantage, particularly in the putting up of-string beans or similarfood products. Of course, when the head is lifted fromthe can-body, theliquid content or brine will drain back into the can.

Referring more in detail to the drawings, I have shown the invention asapplied to a closing machine consisting of a main supportingframe 1carryin a bracket in which is mounted a rotating dicated the support forthe can body, and the raised into proper position for the double seamingof the end on to the body by a double seaming mechanism. A cover feedingmechanism is located above this support 3. In the drawings, the can bodyis in dicated at C. It is about to be moved on to the drum, and thethread 4 will engage behind the can body and move the same along asuitable supporting rail and guide bar to the support 3. These featuresare all of well-known construction, and it is not thought necessary todefine the closing machine more in detail. Attached to this main frame 1is a bracket 5, and mounted on the bracket '5 is a pad 6 is carried by asupporting shaft 7, which not only rotates, but travels bodily so thatthis packing pad 6 remains horizontal, but will move in acounter-clockwise direction as viewed in Fig. 1, and will, therefore,come down into the can, move along with the can for'a short distance,and then rise drum 2. At 3 is inmay. be depressed This percan body whenplaced on this support, is A packing pad 6.. The packing" away from thecan. This packing device is similar to that shown in the patent to FluckNo. 1,307 ,248, granted June 17, 1919. In this prior patent, a plural tyof packing pads are shown and described, while in the drawings, only oneis shown. The deta l structure for supporting and operating th1s ackingdevice as shown in the drawings, orms the subject-matter of a pending aplication of George Flock, Serial No. 45,9 86, flled July 24, 1925. Thepresent invention has to do entirely with the construction of thepacking device and not to the manner of mounting and operating the same.The

packing device 6 consists of a disk-she ed body portion, on the underface of whic is mounted a cutting disk 8. This cutting disk 8 has a deending flange 9, the inner edge 10 of whic tached to the under face ofthis cutting disk is a pad 11. A bolt 12 secures the pad and disk to thepacking device 6. This securing means may be of any desiredconstruction. 7

The pad 11 has an annular recess 13 therein and a series of perforations14 which lead from the face of the pad into the recess. When-thispacking device comes'down on to the cam C, the pad will move into thecan body, while the cutter will move down outside of the can body closeto the flange at the upper end of the can body. Any floating content inthe can body wi 1 be engaged by the cutting edge 10 of the cuttingdevice, and severed. This releases the float-.

ing. content so that the pad 11 will readily force the'same down intothe liquid content of the can. It is very desirable in some instances,such as packing string beans, to

depress the floating content without overflowingl the can. In thepresent-construe tion, t e perforations l4 serve as a means forpermitting the brine or liquid content of the can body to pass up intothe recess 13. Thus it is that the packin down into the can body wit outcausing any overflowing of the same. When the pad is raised from the canbody, the brine or liquid 7 content in the recess 13 will quickly drainback into the can body. It will be understood, of course, that the'pad11 does not make an air-tight contact with the under face of the disk 8,and therefore, the air may I escape from the recess 13 permitting thebrine to flow into the same.

From the above it will be apparent that 'Ihave provided a packing devicewhich insures that the floating content will be depressed into the canbody and drawn off rom the flange so that the flange is freed from-anycontent all the Wayaround. Furthermore, it insures that the floatingcontent may be depressed without causing any is a sharp cutting ed e.At-

pad may move undue overflowing of the liquid content of.

the can body.

It is obvious that minor changes in the details of construction and thearran ement of the parts may-be made without eparting from the spirit ofthe invention as set forth in the appended claims.

Having thus described the invention,

what I claim as new and desire to secure by ing flange with a cuttingedge at the inner side thereof adapted to move down along the flan e ofthe can body for cuttin off any ovei iying content in the can, saidpacking device having a packing pad located within the cutting edge ofsaid disk and spaced therefrom and adapted to move down into the (anbody for depressing the floating content.

3. A packing device for closing machines comprising a packing padadapted to be moved into the can body for depressing the, floatingcontent thereof, and a cutter sur- 7 rounding and spaced from saidpacking pad adapted to move down over the can body v and out off ancontent of the can body overlying the ange of the can body, said padhaving a recess therein, and openings leading from the lower face ofsaid pad into said recess, whereby the liquid in the can i may pass outinto said recess when the pad moves into the can body, and may be drawnback into the can when the pad is raised.

4. packing device for closing machines comprising a cutting disk havinga depending flange with a cutting edge at the inner side thereof adaptedto move down along thelflange of the can body for cutting oif' anyoverlying content in the can, said packing device having a packing padlocated within the cutting edge of said disk and spaced therefrom andadapted to move down into the can body for depressing the Heat.

ing content, said pad having a recess therein, and openings leading fromthe lower face of said pad into said recess, whereby the liquid in thecan may pass out intosaid recess when the pad moves into the can body,

and may be drawn back into the can when the pad is raised.

In testimony whereof, I aflix my signature.
